partition of this knowledge, I summarize the following (just summary, the specific content please yourself search Element): 1. The traditional BIOS only supports booting from the MBR partition's hard disk. The partition table for the MBR partition is stored in the first sector of the hard disk and only 64 bytes, so there can be up to four table entries. In other words, we can only divide the hard disk into 4 primary partitions, or divide it into less than 3 primary partitions plus one extended

The partition table of the MBR partition is saved in the first sector of the hard disk, and only 64 bytes, so there can be up to four table entries.

Extended partitions can also be divided into multiple logical

With the development of technology disk more and more cheap, more and more capacity, at this time we will learn another partition command;The following sections come from a very powerful teacher;When using the Fdisk tool partition, if the partition is larger than 2T, you will be prompted:Value out of range.Therefore, you cannot use the Fdisk partition tool, if you use parted to partition.================================================================

Recursive typeRecursion is closely related to divide-and-conquer methods, since the running time of the divide-and-conquer algorithm can be depicted naturally by using recursion. A recursive formula is an equation or inequality that describes a function by a smaller number of functions on the input. For example, in section 2.3.2, we describe the worst-case run time t (n) of the Merge-sort process with recursion:Θ (1) if n=1T (N) = (4.1)2T (N/2) +θ (n)

TRUE if X is a leaf node, false otherwise2. Each internal node x also contains x.n+1 pointers to their children. (A X.N keyword divides an interval into x.n+1, so there are x.n+1 children, number of children = key Words + 1). Leaf nodes do not have children, so they do not have pointers pointing to the child.3.X.N a keyword to split the range of keywords stored in each subtree.4 Each leaf node has the same depth. That is, the height of the tree H5 The number of keywords contained in each node

in the previous article, we discussed the analysis of loops. Many algorithms are recursive in nature. when we analyze them, we get the recursive relationship of time complexity. The run time we get is the input of size n as the function of N, and the run time of the input of the smaller size. For example, in "merge sort", in order to sort the given array, we divide it into two halves and repeat the two processes recursively. Finally we merge the results. The time complexity of the merge sort can

Cisco router knowledge has become more and more widely used in modern enterprises. Next we will briefly learn about the secure router configuration solution. Knowledge of nine Cisco routers required by network engineers 1. Are the routing protocols supported by Cisco routers compatible with those of other manufacturers? In addition to IGRP and VPN, one of the Cisco routers is that all the routing protocols supported are compatible with the same protocols implemented by other manufacturers. IGRP

than, asymptotic greater than), what is asymptotic, is the difference between the two factors nε. Therefore, between the conditions 1 and 2 there is a certain gap between the same situation 2 and see 3 There is also a certain gap between, for Case 3, but also to see whether the regular conditions are met.Through the above, I believe that I should be clear about these three methods, you may be a little confused, but it doesn't matter, you just lack of examples of guidance, below we look at a few

more than 4 primary partitions for a hard disk with this type of partitioning structure.Here we need to draw out the extended partition:An extended partition is also a primary partition (Primary partition), but it differs from the primary partition in that it can theoretically be divided into countless logical partitions, each with an extended boot record (EBR) similar to the MBR structure. In the MBR partition table, up to 4 primary partitions or 3 primary partitions + one extended partition,
